<p>The hydraulic adjuster is especially for tractor three point linkages and consists of a single-acting piston/cylinder unit. As well as the adjusting piston/cylinder unit, there is a double-acting, further piston-cylinder unit (7, 10) of smaller diameter used as an arresting device. There is a control implement which allows a hydraulic oil flow from one side of the piston (10) to the other as soon as the control lever for the adjusting unit is brought out of the neutral position. The double acting piston-cylinder unit has a smaller diameter than the adjusting unit (6, 9).</p> |
